Gas in oil drip from drive shaft engine connection area?

[Revive]

5 years of no use and have a leak. Did compression test on all cylinders. 2 fire well and have 110+ ....2 not firing 95 + compression. Replacing distributor cap, wires, plugs oil change and will try starting this week. Also had gas as chalky mixture in exhaust outflow. Gas due to non firing cylinders I assume.
Any suggestions?

Is this gas on the exterior of the engine? If it is, you need to trace the fuel path looking at connections carefully until you find the leak.

One place in particular is the bowl of a mechanical fuel pump (if you have one).
